WILLIAM E. CBIST, OF

VENTILATED JOURNAL-BOX.

Original application med December 9,

To all :Lf/1.0m t may concern.'

Be it known that I, lVILLIAu E. C ms'r, a citizen of the United States, residing 1n HBaltimore city and State of Maryland, have invented a` new and useful Improvement in Ventilated Journal-Boxes, of which the following is a specification. i'

This invention relates to improvements 1n `ventilated journal boxes, and more partielllarly to those used on railway locomotive tenders, passenger, freight and other car boxes-which have the journal boxes located on the axlesfoutsideofthewheelS, but it will `be understood that the invention may be.

. within the journal box, the heated or foul air Within the box being constantly replaced by coolerlair from the atmosphere, this circulation being caused by the increased pressure of the atmosphere on one side of the journal box, namely, the advance or forward side when the 'train is moving. and the decreased pressure of the atmosphere on the -rear side of the journal box.

Another object of the invention is to pro- 4 vide means for Ventilating the interior of journal boxes in such a way that the air will circulate about and around the end and undersides of the axlojournals` thus cooling the axle journals on their outer surfaces, as contradistinguished from former types of ventilated journal boxes where the air is passed through perfor-ations in the axles.

Still another object of the invention is to provide means for VVentilating theI interior of journal boxes which are applied to the lid or cover of the journal box, so that the improved form of lid or cover may be applied to journal boxes alreadyr in uso by merely replacing the old, plain form of lid.

The invention furthermore consists in the improvements in theparts and devices and in the novel combinations -of parts and rle vices herein shown, described or claimed.

In the drawing forming a part of this specification, Figurt` 1 is a side elevation of a journal box showing my in'iprovcmcnts in connection there-with. Fig. Qis an elevation speciacanoirof Letters Patent.

oted at 14 to the journal box, but as .will be obvious to those skilled in the art, the lid or cover may be otherwise secured to the jour. nal box' than as shown. The lid is Provided with a. raised or outstanding porti'onfl, which' is provided with a pair of air passageways 16, 16, separated by a partition or rib 16, each having'a substantially vertical, inlet orifice 17` said inlet. orifices facing in opposite directions so that air will always be. forced through the front passageway 16, as shown hy the arrows a, when the train is moving in the direction indicated by the arrow b, depending upon 'the direction of movement of the car u'pon which the journal box is mounted. Th'e cover or lid 4is also provided with, a pair of air inlet and outlet orifices 1S. 18, each orifice 18 communicating directly with the interior of the journal box, and also bv means of passagewavs 19, 19 with the other air passagcways 1G. 16. As air is forced through either passageway lt, as vshown for instance by the. arrows n, air will be withdrawn from the interior of the journal box through one. ofthe-orifices 18 through the passageway 19 in the manner indicated by thc arrows e. duc to the de4 creased pressure within the passageway 19 created by the draft of air' through the passageway 1G. As air is withdrawn from the interior of the journal box through oneV 0f seul in n groove 22 l'oinn-tl in the null ol' the. orilii-e. see Vig. l.
